Deform-Proof Cup

ABSTRACT

A novel cup is revealed. The cup is deform-proof. A body part of the cup has lateral-oriented fibers. By using the lateral-oriented fibers together with a rim part surrounding an opening part of the cup, the cup is not easily deformed on being held by hand. The present invention can be applied to cups with different heights for strengthening the body part, reducing weight of the body part and lowering production cost.

TECHNICAL FIELD OF THE INVENTION

The present invention relates to a cup; more particularly, relates tousing lateral-oriented fibers in a body part together with a rim part toprevent the cup from deformation on being held by hand, where thepresent invention can thus be applied to cups with different heights forstrengthening the body part, reducing weight of the body part andlowering production cost.

DESCRIPTION OF THE RELATED ART

A general paper cup comprises a body part of lateral-oriented fibers, anopening part on top of the body part and a closing part at bottom of thebody part. With the paper cup, a drink is held to be drunk.

Although, the lateral-oriented fibers of the body part is used, thefibers may still be broken (perpendicularly) by a force of the user'shand when the height of the body part is longer than the diameter of theopening part (i.e. a tall cup with volume more than 500 cubiccentimeters (cc)). Consequently, stiffness of the body part will be lostand the body part may further be deformed, which means the body part isnot suitable for the tall cup with the height of the body part longerthan the diameter of the opening part.

Hence, the prior art does not fulfill all users' requests on actual use.

SUMMARY OF THE INVENTION

The main purpose of the present invention is to use lateral-orientedfibers in a body part together with a rim part to prevent a cup fromdeformation on being held by hand, where the present invention can thusbe applied to cups with different heights for strengthening the bodypart, reducing weight of the body part and lowering production cost.

To achieve the above purpose, the present invention is a deform-proofcup, comprising a body part, an opening part, a rim part and a closingpart, where the body part comprises a plurality of lateral-orientedfibers; the opening part is set on top of the body part; the rim part isset to surround the opening part; and the closing part is set at bottomof the body part. Accordingly, a novel deform-proof cup is obtained.

BRIEF DESCRIPTIONS OF THE DRAWINGS

The present invention will be better understood from the followingdetailed descriptions of the preferred embodiments according to thepresent invention, taken in conjunction with the accompanying drawings,in which

FIG. 1 is the view showing the first preferred embodiment according tothe present invention;

FIG. 2 is the sectional view showing the local area of the firstpreferred embodiment; and

FIG. 3 is the view showing the second preferred embodiment.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

The following descriptions of the preferred embodiments are provided tounderstand the features and the structures of the present invention.

Please refer to FIG. 1 and FIG. 2, which are a view showing a firstpreferred embodiment according to the present invention; and a sectionalview showing a local area of the first preferred embodiment. As shown inthe figure, the present invention is a deform-proof cup, comprising abody part 1, an opening part 2, a rim part 3 and a closing part 4.

The body part 1 comprises a plurality of lateral-oriented fiber 11.

The opening part 2 is set on top of the body part 1.

The rim part 3 is set to surround the opening part 2.

The closing part 4 is set at bottom of the body part 1.

Thus, a novel deform-proof cup is obtained.

Therein, the body part 1, the rim part 3, and the closing part 4 aremade of paper and height of the body part 1 is longer than diameter ofthe opening part 2 (i.e. a tall cup having a volume more than 500 cubiccentimeters (cc)).

On using the present invention, the body part 1 contains a drink for auser to drink. When the user holds the body part 1 with his hand, aforce is usually put on middle or lower part of the body part 1. Thus,upper part of the body part 1 receives a smaller force (which can bealmost reduced to none). Therefore, the upper part of the body part 1can use the lateral-oriented fibers 11 to maintain proper stiffness forstrengthening the body part 1. Hence, on holding the body part 1, thelateral-oriented fibers 11 are used to prevent deformation. Furthermore,because the upper part of the opening part 2 and the rim part 3 are notaffected by the user's holding the body part 1, the rim part 3 can bemade of paper.

Please refer to FIG. 3, which is a view showing a second preferredembodiment. As shown in the figure, a body part 1 a and a closing part 4a of a cup fabricated according to the present invention are made ofpaper. A rim part 3 a of the cup is made of plastic. Height of the bodypart 1 a is shorter than diameter of the opening part 2 a (i.e. a shortcup). The plastic is polyproylene (PP), polyethylene (PE), polyethyleneterephthalate (PET), a biomaterial, a biodegradable material, polylactic acid (PLA) or a biomass plastic. Thus, strength of the body part1 a is maintained by the plastic rim part 3 a, which further reducesweight of the body part 1 a and lowers production cost.

To sum up, the present invention is a deform-proof cup, where, by usinglateral-oriented fibers in a body part together with a rim part, a cupwill not be easily deformed on being held by hand; and, thus, thepresent invention can be applied to cups with different heights forstrengthening the body part, reducing weight of the body part andlowering production cost.
